Abstract

L'invention concerne un système d'alimentation électrique (12) de four à arc électrique (10) qui comprend une entrée de courant alternatif (20) pouvant être connectée à une grille électrique (22) et une sortie de courant alternatif (24) servant à alimenter au moins une électrode de puissance (14) du four à arc (10) ; un circuit résonnant (46a, 46b, 46c) interconnecté entre l'entrée de courant alternatif (20) et la sortie de courant alternatif (24). Le circuit résonnant (46a, 46b, 46c) comprend un commutateur de dérivation apte à être commandé (60) pour connecter et déconnecter une entrée de circuit (56) et une sortie de circuit (58) du circuit résonnant (46a, 46b, 46c) et un condensateur (64) et une bobine d'induction principale (66) connectés en parallèle avec le commutateur de dérivation (60).
